DECLARE @XMLString table
(xmldata xml)
insert into @XMLString(xmldata)(select xmldata from dbo.Stg_XmlFile where id =51)
--insert into stg_RelationalData
SELECT
----level
CAST(x.y.query('//level/title[1]/text()') as varchar(255)) AS title
, cast(x.y.query('//level/description[1]/text()') as varchar(255)) AS [description]
----level_year
, cast(x.y.query('//level_year/year[1]/text()') as varchar(255)) AS [year]
, cast(x.y.query('//level_year/code[1]/text()') as varchar(255)) AS code
, cast(x.y.query('//level_year/default[1]/text()') as varchar(255)) AS [default]
FROM @XMLString
CROSS APPLY xmldata.nodes('//level_year') as x(y)
my result set gives doubles:
title description year code default
havo havo 12 havo1havo2 truetrue
havo havo 12 havo1havo2 truetrue
what i really would like is:
titel description year code default
havo havo 1 havo1 true
havo havo 2 havo2 true
:hehe:

Can you post your XML (as an attachment if possible)

Posting XML in the forum directly doesn't work.

Attach it as a text file.

I think the problem is in your XPath expressions, not with the CROSS APPLY clause:

Does this give you what you are expecting?

SELECT

----level

CAST(x.y.query('../../title[1]/text()') as varchar(255)) AS title

, cast(x.y.query('../../description[1]/text()') as varchar(255)) AS [description]

----level_year

, cast(x.y.query('./year[1]/text()') as varchar(255)) AS [year]

, cast(x.y.query('./code[1]/text()') as varchar(255)) AS code

, cast(x.y.query('./default[1]/text()') as varchar(255)) AS [default]

FROM @XMLString

CROSS APPLY xmldata.nodes('//level_year') as x(y)

Running this against the Finally.xml file gives this result set.

[font="Courier New"]title description year code default

hi andrewd.smith well finally it is working yes. I understand that the nodes are not neaded. Only the element names in the nodes and that the path to the element names is like ../../

i am know going to put the results in SSIS and use them in a table difference.

Thanx very much!!

Regards,

Sjaak

Where is this sytax documented at? Specifically the last bit after the cross apply, i.e. 'as x(y)'. And the references in the query to it, i.e. 'x.y.query('...'

What is that doing/how does it work/where can I find it in the BOL?

Thanks!
